Who said “All achievement, all earned riches, have their beginning in an idea! p.18”?

“Ideas too are a life and a world.”

“It is ideas, not vested interests, which are dangerous for good or evil.”

“An idea that is not dangerous is not worthy of being called an idea at all.”

“If you are possessed by an idea, you find it expressed everywhere, you even smell it.”

“Ideas are refined and multiplied in the commerce of minds. In their splendor, images effect a very simple communion of souls.”

“If you do not conquer self, you will be conquered by self.”

“No man can succeed in a line of endeavor which he does not like.”

“Any idea, plan, or purpose may be placed in the mind through repetition of thought.”

“Do not wait; the time will never be ''just right.'' Start where you stand, and work with whatever tools you may have at your command, and better tools will be found as you go along.”

“Think and grow rich.”

“You give before you get.”
